It will I am continuing my searches for the problem and just have been able to find out this: USER PID %CPU %MEM VSZ RSS TT STAT STARTED TIME COMMAND www 44888 100.0 0.2 5976 3644 ?? R 11:46AM 2:35.18 /usr/sbin/httpd (perl5.8.9) root 14 96.3 0.0 0 8 ?? RL Fri08AM 7161:12.89 [idle: cpu0] www 44887 96.3 0.2 5976 3644 ?? R 11:46AM 2:34.58 /usr/sbin/httpd (perl5.8.9) The process dies as soon as it ends. But this is strange: $ l /usr/sbin/httpd ls: /usr/sbin/httpd: No such file or directory So it looks like these two processes made the machine unresponsive and generated a lot of outgoing traffic. However, the file does not exist. Any hint as to how to debug it further? I am determined to find the culprit. Thanks! -- Zbigniew Szalbot www.slowo.pl www.fairtrade.net.pl
